THE THAR DESERT, often called the Indian Desert, extends for about 400 mi (644 km) from southwest to northeast and has a maximum width of about 225 mi (362 km).
The desert is limited to the south by the Great Rann of Cutch.
To the west lies the valley-plain of the INDUS RIVER and to the northwest that of the Sutlej.
Northwestward the desert fades into the Punjab state of INDIA, and the Aravalli range marks the southern limit.
The greater part of the desert lies in the Indian state of Rajasthan, of which it occupies nearly half.
The remainder is in PAKISTAN, where the desert occupies a large part of the former princely state of Bahawalpur and the old province of Sindh.
The greater part of the desert surface is composed of sands, silts, and loesslike material, the finer-grained making excellent soil where water is available.
The name Thar (desert or sandy waste) refers to the sand hills accumulated by the prevailing winds.
Saline dust is transported from the Indus delta and the Rann of Cutch and deposited in hillocks.
In the southwest, long ridges (in local Sindhi language, bhits) are found aligned from southwest to northeast parallel to the prevailing winds.
In the northeast, these give place to transverse dunes of barchan type, though they are somewhat irregular.
Toward the Rann, dunes more or less permanent may rise to 200 ft (76 m) above the general sandy surface; inland they are smaller.
The average rainfall in the area is 15 in (38.1 cm) a year and on the western margins near the Indus this drops to less than 5 in (12.7 cm).
Temperature varies from 55 degree F (13 degrees C) to -70 degree F (-21 degrees C) in the cold season and from 90 degrees F (32 degrees C) up to 127 degrees F (53 degree C) in the warm season.
Dust storms are common at the periods of reversal of pressure, about April to May and during October.
Surface deposits everywhere are impregnated with salt derived from the evaporation of subsoil brine and the accumulation of salt particles blown from the Rann.
On the eastern margins of the desert are the Rajasthan salt lakes.
Lake Sambhar, the largest, lies in a closed depression in the Aravalli schists with a surface at 1,184 ft (361 m).
- The capital city of Bulgaria opened a new museum
"The children-oriented museum invites them to explore the environmental world in a game style.
The so-called “Museiko” museum has been located at the kids’ centre in Sofia. Young explorers are able to go back to the past and gasp the meteorites dropped on our planet. There are also a lot of entertainment activities for kids: they will be offered to look at the world through the frog’s eyes, try their hands in archeology and construction, and puzzle out the nature mysteries and many other things.
At different levels of the museum children and parents are able to find themselves at various time spaces, which are the past, the present and the future. They will not only get the idea of the all possible opportunities in different scientific fields, but also will be able to play games on anxiety development and love to the activities in creativity. Besides this, different accelerated learning techniques will be used while working with young visitors. "
- Sightseeing in Greece will become much more expensive
"Greek authorities reported about a sharp increase in price for visiting museums and other places of interest around the country. In particular, starting from January 1, 2016 the ticket price at Acropolis will reach 52 euro. Today the Athens main attraction costs only 12 euro.
The entrance ticket price to the sanctuary of Olympia and Knossos ruins will be raised twice. Since the beginning of the next year 200 museums located all around the country will also increase the ticket price.
However, the Greek authorities note that such high prices are likely to be up to date only during the summer tourist season. "
